I wish they'd do a more expensive version with a better speaker, or even license it so other manufactures could just chuck the tech in their speakers. I know you can link it up with other speakers but its not quite as tidy a solution.
So your "wish" has begun to be answered it seems with yesterday's announced introduction of a few new speakers from Anker, Panasonic and Mobvoi because Google has opened up the Google Assistant SDK to permit anyone to embed GA into almost anything. As far as hardware is concerned, GA is getting embedded into more and more attractively priced products, but I would like to see more devs taking up the software side because the Google AI that sits behind all this hardware seems very impressive.
At the moment, when I finish my day with the Nest Thermostat, the Philips Hue lightbulbs, the IFTTT enabled smart kettle and hopefully soon the connection to a vacuum cleaner, a sprinkler and LG appliances such as a washer, a dryer, a dishwasher, etc (announced tie-ups yesterday), I have to still give individual instructions to Google Home to regulate each smart device. I would like to see better and smarter software integration where I can control all these devices at the same time with one voice command---eg, OK Google good morning means the device knows what devices I want to automatically start-up knowing my history of individual actions before or similarly what I want closed or put on timer in the evening when I say OK Google, goodnight. I assume that as more and more hardware gets integrated with GH, there will be more of this need?
